Number patterns
Reference pages for the patterns behind RNGdle rolls — definitions, examples, and how many values fit between 0 and 1,000,000.
How to use it
Open a topic, read the rule, skim the examples. When you want a full EP breakdown for one number, use the calculator. For unlimited practice, try infinite.
